(54) System and method for spread spectrum code position modulation and wireless local area network employing the same


(57) A system for, and method of, generating a spread spectrum code position modulated waveform and a wireless local area network (LAN) containing the system or the method. The system includes: (1) a spread-spectrum encoder that receives and encodes portions of an information signal with a multi-chip code having a predetermined length to create therefrom a stream of sequences, each of the sequences having the predetermined length and (2) a transmitter that periodically transmits the each of the sequences at a time interval that differs from the predetermined length, a data rate of transmission of the information signal thereby allowed to increase.
